class owlcpp::Map_triple< Index_subj, Index_pred, Index_obj, Index_doc >

void owlcpp::Map_triple< Index_subj, Index_pred, Index_obj, Index_doc >::erase ( Triple const &  t )

inline

erase one triple

Parameters

t	triple stored in triple map

Exceptions

Rdf_err

exception if triple is not found

template<bool Index_subj, bool Index_pred, bool Index_obj, bool Index_doc>

template<class Subj , class Pred , class Obj , class Doc >

result<Subj,Pred,Obj,Doc>::type owlcpp::Map_triple< Index_subj, Index_pred, Index_obj, Index_doc >::find ( const Subj  subj, const Pred  pred, const Obj  obj, const Doc  doc  ) const

inline

Search triples by subject, predicate, object, or document IDs.

Polymorphically search stored triples to find ones that match specified node IDs for subject, predicate, or object nodes or document ID. An instance of any matches all values for the corresponding triple element. If none of the nodes are specified, i.e., find(any(), any(), any(), any()), the search returns a range of all stored triples, [begin(), end()).

Parameters

subj	predicate for first element of triple (subject node), e.g., Node_id, any
pred	predicate for second element of triple (predicate node), e.g., Node_id, any
obj	predicate for third element of triple (object node), e.g., Node_id, any
doc	predicate for fourth element of triple (document ID), e.g., Doc_id, any

Returns

iterator range of triples matching the query.

The type of the range can be obtained from

template<class Subj, class Pred, class Obj, class Doc> class result; 

or from

template<bool Subj, bool Pred, bool Obj, bool Doc> class result_b; 

For example,

Triple_map<>::result_b<1,0,0,1>::type range = triple_map.find(subj, any(), any(), doc);

template<bool Index_subj, bool Index_pred, bool Index_obj, bool Index_doc>

std::size_t owlcpp::Map_triple< Index_subj, Index_pred, Index_obj, Index_doc >::size ( ) const

inline

Returns

number of stored triples
